SPECIFICATION forming part of Letters Patent No. 781,349, dated January31, 1905.

i Application filed May 23, 1904. Serial No. 209,244. ($peeim6ns.)

To all whom it may concern:

Be it known that I, GEORGE D. MOORE, a citizen of the United States,residing at Worcester, in the countyof Worcester and State ofMassachusetts, have invented a new and useful Method of Weaving MultipleTubular Fabrics and a Hose-Covering Produced Thereby, of which thefollowing is a specification. v T

This invention relates to a method of weaving flattened concentrictubular fabrics.

The object of this invention is to employ fiat weaving forthe productionof certain special fabrics the production of which has here- I5 toforebeen accomplished only on circular looms or by circular weaving.

' A further object of this invention is to provide a new fabric designedfor use as a hosecovering which will be more durable than ordinaryhose-coverings by reason of the fact that it can be more readilyflattened andflexed.

To these ends this invention consists of the method of weaving and ofthe special fabric produced thereby, as hereinafter described,

and more particularly pointed out in the claims at the end of thisspecification.

In the accompanying drawings, Figures 1 to 6 are diagrammatic viewsillustrating successive steps in weaving a fabric according to 3 thisinvention. Fig. 1 illustrates the travel in one direction of the shuttlewhich forms the inner tube. Fig. 2 illustrates the travel in onedirection of the shuttle which forms the outside tube. Fig. 3illustrates the-return travel of the shuttle which forms the inner tube.Fig. 4 illustrates the return travel of the Shuttle which forms theoutside tube. Fig. 5 illustrates an operation similar to that shown inFig. l-taking place in connection 4 with a subsequently-formed shed, andFig. 6 illustratesan operation similar to that shown in Fig. 2 takingplace in connection with a subsequently-formed shed. Fig. 7 is adiagramniatic sectional View of the completed fabric, showing thearrangement of binder-warps employed to form a special fabric forhosecoverings; and Fig. 8 is a'perspective view of a piece of thecompleted fabric.

In weaving certain classes of fabrics, par-- ticularly in weavingmultiply hose-coverings employed for the better grades of fire-hose, ithas heretofore been deemed necessary to use circular looms and to employthe circular process of weaving. A circular loom is a com parativelyexpensive piece of apparatus, and the operation of a circular loom isconsiderably slower than theprdinary flat-weaving operations which areperformed in the ordinary looms. By practicing my invention I have beenenabled to produce a superior quality of this class of fabrics upon aflat loom and at a comparatively high speed. In addition to this mymethod may also be employed for weaving fabrics for other purposes-such,for example, as the fabrics required for belting or for other purposes.

Referring to the accompanying drawings for a detail description of theway my invention is carried out, as shown diagrammaticallyinFigs. 1 to6, the warp threads are divided to open a number of sheds. In thepresent drawings I have illustrated my invention as applied to theproduction of a two-ply tubular fabricthatis to say, to the productionof two simultaneously-woven flattened concentric tubes. It'is to beunderstood, however, that my invention is also applicable to theproduction of fabrics comprising a greater number of concentricflattened tubes.

As shown in Figs. 1 to 6, the warp-threads are divided to form fourdistinct shedsviz., the top and bottom sheds 10 and 13, which form theoutside tube, and the intermediate or central sheds ll and 12, whichform the inclosed tube. In practicing my invention the shuttle A, whichoperates in the formation of i I the inside tube is first insertedthrough the shed 12. The shuttle B, which operates in the formation ofthe outside tube, is next inserted through the shed 13, as shown in Fig.2. The shuttle A is then returned through the lower intermediate shed11, as shown in Fig. 3, and the shuttle B is returned through the bottomshed 10, as shown in Fig. 4. This completes one cycle of the method ofweaving the fabric, and the sheds are then shifted so that at the nextoperation the shuttle A is passed through the next succeeding orsubsequently formed shed, as shown in Fig. 5, and the shuttle B ispassed through the subsequently formed shed, as shown in Fig. 6. In theparticular construction illustrated two concentric tubes T and T will bewoven flat, as illustrated diagrammatically in Fig. 7.

This method of weaving tubular fabrics can be practiced with especialadvantage in looms having a number of reed-spaces, and when such a loomis employed in practicing this invention the number of shuttle-boxes maybe one less than the number of fabrics produced.

The fabric woven according to this invention consisting of the twoflattened concentric tubes T and T may have its different plies orlayers tied together by means of bind er-warps, according to theparticular use for which it is intended to employ the fabric. Forexample, by using binder-warps, binding all four of the plies together,and especially by using binder-warps extending from each outside plyonly part way through the combined thickness of all plies, I am enabledto produce a flexible and strong belting, as shown, for example, in mycompanion application for patent executed by me on even date herewith,Serial No. 209,245, filed May 23, 1904.

When a fabric produced according to this invention is to be employed asa hose-covering, I use a number of binder-warps W for stitching adjacentportions of the two concentric tubes T and T together.

The binder-warps W may be used, if desired, to unite the entirecircumference of the two tubes T and T; but in practice and asillustrated in Figs. 6 and 7 I preferably use two series of binder-warpsWV, leaving two unconnected strips or sections at opposite sides of thetubes. This provides a form of fabric particularly adapted for use as afire-hose covering.

In ordinary fire-department use the greater part of hose employed is nowcarried in hosecarts or in special hoseteams, the hose being folded intolengths to lie upon the bot toms of the carts. By leaving comparativelyflexible sections at opposite sides of the hosecovering, as shown, forexample, in Fig. 7, the hose may be readily flattened and can be foldedto the desired length without creasing the fab ric and without strainingthe same to such i is provided with a rubber lining in the ordinarymanner.

I am aware that numerous changes may be made in practicing my inventionby those who are skilled in the art and in my new fabric forhose-coverings. I do not wish, therefore, to be limited to the detailsof operation or construction which have been herein set forth; but

hat I do claim, and desire to protect by Letters Patent of the UnitedStates, is-

1. The method of weaving flat concentric tubular fabrics which consistsin arranging warp-threads to open a number of sheds, inserting oneweft-thread through one of the intermediate sheds, inserting a secondand distinct weft-thread through the upper shed, returning the firstweft thread through another intermediate shed to form an inclosed tube,and returning the second weft-thread through the bottom shed to form anoutside tube.

2. The method of weaving two concentric flattened tubes which consistsin arranging warp-threads to open four sheds, inserting one weft-threadthrough one of the intermediate sheds, inserting a second separate anddistinct weft-thread through the upper shed, returning the firstweft-thread through the other intermediate shed to form the inclosedtube, and returning the second weft-thread through the bottom shed toform the outside tube.

3. The method of weaving concentric tubular fabrics for use as ahose-covering, which consists in arranging warp-threads to open a numberof sheds, inserting one weft-thread through an intermediate shed,inserting a second and distinct weft-thread through the upper shed,returning the first weft-thread through another intermediate shed toform an inclosed tube, returning the second weft-thread through thebottom shed to form an outside tube and fastening said tubes together bybinder-warps.

4E. Themethod of weavinga fabric comprising two concentric flattenedtubes for use as a hose-covering which consists in arrangingwarp-threads to open four sheds, inserting a weft-thread through one ofthe intermediate sheds, inserting a second separate and distinctweft-thread through the top shed, returning the first weft-threadthrough the other intermediate shed to form the inclosed tube, returningthe second weft-thread through the bottom shed to form the outside tube,and in fastening the said tubes together by binderwarps around part onlyof their circumferences.

P781349 I Q 5. As an article of manufacture a hosecovcring fabricconsisting of concentric tubes secured together by binder-warps for partonly of their circumferences, whereby said fabric may be readilyflattened and folded.

6. As an article of manufacture a hosecovering fabric consisting of twoconcentric tubes secured together by binder-warps on two oppositeportions of their circumferences,

leaving flexible or hinged sections at opposite I0 sides of the tubes.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses,.- r
